Mr A. P. Bigelow introduced a towel rental service to businesses in London. Each towel was marked with the customer's initials, which ensured that customers only received their own towels, leading to the name, 'Initial Towel Supply Company'.
Danish pharmacist, Georg Neumann of Aalborg discovered a strain of bacteria lethal to rats and mice, which became known commercially as Ratin. The first London sales office opened in 1906.
Harold Maxwell Lefroy, Professor of Entomology at Imperial College London, was asked to study ways of exterminating the beetles in Westminster Hall and in time began receiving regular orders.
Lefroy started supplying bottles of woodworm fluid from a small factory in Hatton Garden, which he called 'Ento-kill fluids - an amalgam of the Greek work 'entomon' meaning insect and the English word 'kill'.
Rentokil is born.
The company was registered in 1925 as Rentokil Limited due to trade name objections preventing the name 'Entokill'.
The Initial Towel Supply Company floated on the stock market and during the 1930s BET (British Electric Traction) acquired a small stake in Initial.
